Title: Electrical heating element assemblies
IPC: H05B3/16
Filed: 1972-12-07
Abstract: 1364919 Crimp corrections STANDARD TELEPHONES & CABLES Ltd 7 Dec 1972 [29 Sept 1971] 45369/71 Heading H5H [Also in Division H2] To prevent strain on resistance wire 10 from the leads 30, the lead support plate 38 and the adjacent wire support 16 have apertures 40b, 22 sufficiently small that the crimp connector 32 can not pass therethrough, the connector thus acting as a stop. The lead support may be a resilient plastics, e.g. epoxy glass, so that the apertures 40b may be connected to the edge of the plate by slots 40a of smaller width than the wire. The apertures in the wire supports may also be extended to a side portion. The supports 16 are of a ceramic material and slot into metal plates 12, 14. The crimp connector is of copper or soft brass and has an enlarged portion 34 to prevent the connector passing through aperture 22. The plates 12, 14 can form part of an outlet duct of a tangential fan heater. The element assembly may be used in a hair drier.

Title: Data processing system timing
IPC: G06K17/00
Filed: 1965-10-26
Abstract: 1,134,003. Record controlled typewriters; timing. SCM CORP. 26 Oct., 1965 [26 Oct., 1964], No. 45371/65. Heading G4H. In a data processing system comprising a record medium having coded data recorded thereon in intermixed positions for controlling both a printer and also devices other than the printer, the reader for the record medium being operable at a rate faster than the printer can accept, means are provided for interrupting the reader only when two printer control codes follow one another within a predetermined time period. As described, the data processing system includes a typewriter, two paper tape readers (only one of which is normally operative at a time), a paper tape punch and an optional computing unit. Sensing of data by the readers is controlled by a multivibrator operating (for example) at 30 c.p.s. Whenever a typewriter control code is sensed a monostable multivibrator is triggered to indicate a " decode busy " state. This prevents typwriter response to a further code for 72 m.s. (for example). Thus when, for example, two characters to be printed are read in succession, advance of the paper tape in the reader is interrupted and the second character is repeatedly sensed until the " decode busy " state generated by sensing of the first character is ended. The reader immediately advances to the next reading position on reading a code for controlling a device other than the typewriter. Means are provided for extending the inhibiting effect of the decode busy state when prolonged typewriter functions such as carriage return or tabulation are sensed. Alphanumeric data may be written into the computing unit or punch during this prolonged inhibition period (parallel processing). The logical arrangement of the system for achieving the above operations is described in great detail with reference to the 16 drawings. Also described is an arrangement whereby one reader may be skipped (in search of a predetermined control code) at the same time as the other reader is providing data in the above described manner without the need for dual circuits and separate timing generators-cf. Specification 1,134,005-a field control arrangement by which various parts of the system can be controlled by the position of the carriage (using eight channel perforated paper tape secured to said carriage and sensed electrically, the sensing being operative only after depression of one of the typewriter keys)-cf. Specification 1,134,006-and a single step feed arrangement for the tape and the paper tape punch (used for preparation of the field control tapes already referred to)-cf. Specification 1,134,004. The input media may be in the form of punched paper tape or cards, magnetic tape or cards or photographic film.

Title: Improvements in or relating to variable gain transistor amplifiers
IPC: H03G3/30
Filed: 1962-12-03
Abstract: 1,017,759. Transistor amplifying circuits. PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd. Dec. 3, 1962 [Dec. 6, 1961], No. 45613/62. Heading H3T. In a transistor amplifying circuit wherein the emitter collector path of a first transistor is connected in series with that of a second transistor from the collector of which the output is taken, gain control means are provided to vary the D.C. voltage difference between the bases of the two transistors and means are provided to maintain the D.C. emitter current of the first transistor substantially independent of the gain control means so that as a result of the control the D.C. collector current of the first transistor may decrease to a considerably smaller value than its emitter current. The circuit of the Figure shows an I.F. amplifier stage of a radio receiver in which input signals are applied over tuned circuit 2 and winding 3 to the base of transistor 4 the emitter collector path of which is connected in series with that of a second transistor 5 in the collector circuit of which is a tuned I.F. output circuit 6. The gain of transistor 4 is controlled in accordance with a voltage V proportional to the average amplitude of the signal oscillations and derived from the detector of the receiver and applied to the base of transistor 5. If the signal amplitude at the terminals increases, the control voltage at the base of transistor 5 decreases, i.e.. becomes less negative, with the result that the collector voltage of transistor 4 decreases so as to reduce the gain of the transistor. Due to resistor 10 in the emitter circuit of transistor 4 the D.C. emitter current of this transistor is fixed at a value determined by resistor 10 and potentiometer 12, 13 and if the collector voltage of transistor 4 decreases to a value such that the emitter-collector voltage difference is very small the D.C. collector current decreases further below the value of the emitter current and the gain is further decreased. The circuit may be used at high frequencies, e.g. 200 mc/s. and further gain control may also be obtained by applying V to the base of transistor 4 as well as to transistor 5. A diode 16 operating in the reverse direction may be connected as shown to a point of constant potential so as to extend the range of control further.

Patent GB-1441775-A (GB)
Title: Methods of testing a functional logic system
IPC: H01L21/822
Filed: 1973-10-01
Abstract: Level sensitive testing is performed on a generalized and modular logic system that is utilized as an arithmetic/logical unit in a digital computer. Each arithmetic/logical unit of a computer is formed of arrangements of combinational logic networks and storage circuitry. The storage circuitry has the capability for performing scan-in/scan-out operations independently of the system input/output and controls. Using this scan capability, the method of the invention provides for the state of the storage circuitry to be preconditioned and independent of its prior history. Test patterns from an automatic test generator are cycled through the networks of combinational logic and their respective associated storage circuitry for removal through the scan arrangement to determine their fault status.

Abstract: 1,090,870. Capacitors. INTERNATIONAL STANDARD ELECTRIC CORPORATION. Oct. 14, 1966 [Oct. 19, 1965], No. 45941/66. Heading H1M. Corrugations on the annular portion 5 of end cap 4 allow the cap to move outwardly in response to increase in pressure within the sealed capacitor container 1, and when this happens, lead 8 is severed by the edges of aperture 15 of a spigot 13 on the cap and of the centre aperture 17 in plate 16. Alternatively, as in Fig. 2, both leads 8 and 9 pass through the aperture 15, and the shearing action on increase of pressure cuts through the insulation of lead 9 to effect a short circuit between it and bare lead 8. By this means an external protective device may be tripped. The capacitor may be electrolytic.

Title: Process for coating nuclear fuel particles with pyrolytic graphite
IPC: C01B31/00
Filed: 1963-11-25
Abstract: Nuclear fuel particles, e.g. uranium or thorium carbides, are coated with pyrolytic graphite by heating to a temperature slightly below their surface sintering temperature in a mixture of inert gas diluent and hydrocarbon gas of volume ratio from 3:1 to 20:1, for a period of time sufficient to deposit a layer or laminar pyrolytic graphite or a thickness of from 5-50 microns on the particles, and further heating the thus coated particles to a temperature of at least 1800 DEG C. in a gaseous mixture as above but of volume ratio from 7:1 to 20:1 for a period of time sufficient to deposit a layer of columnar pyrolytic graphite of the desired thickness on the particles.  Suitable hydrocarbons are benzene, methane, ethane, propane, butane, ethylene, propene, butene, pentene, acetylene, cyclobutane, cyclopentane, cyclohexane, cyclobutene and cyclopentene, while suitable inert gas diluents are argon, helium and hydrogen.  After the first coating step, the particles may be washed in an acid bath at from 90-98 DEG C. to eliminate any surface contamination and to dissolve any particles which may be uncoated and therefore would tend to sinter at high temperatures.  In one example, UC2 particles having a surface sintering temperature of 1775 DEG C. are heated at between 1700 DEG C. and 1750 DEG C. in the first coating step and at 1800 DEG C. in the second coating step.

A jack for lifting an underground transfer conveyer with a frame 1 and endless belt 3 comprises a housing 6 with fluid pressure connections 17, 18 below and above a hollow piston 8 sliding therein. An aperture 19 interconnects the upper part of the cylinder 8 to the upper part of the housing 6. The piston 8 has a hollow extension 9 passing through a seal 16 in a support plate 7a mounting the housing and a tubular member 7. A cylinder 23 is mounted on the member 7 and has a piston 21 with an abutment 20 normally urged by a spring 22 into engagement with one of a series of notches on the extension 9 to lock the extension 9 to the member and thus hold the piston 8 fixed in the housing 6. A piston 10 slides in the piston 8 and has a hollow piston-rod 11 extending therefrom through the member 7 and with a groundengaging foot 12. The piston 10 is urged to its uppermost position in the cylinder 8 by a spring 13. The jacks are attached in pairs to sections of the conveyer by pairs of struts la. In the transport position brackets 25 attached to the housings 6 engage the tops of mine cars 26 as shown in Fig. 3. At the desired position cylinder 23 is pressurized, releasing the extension 9 allowing the piston 8 and piston 10 to drop under gravity until the foot 12 contacts the ground. The cylinder 23 is then vented and piston 8 thus locked with respect to the housing 6. Pressure fluid is then supplied to connection 18 causing the piston 10 to move from the top to the bottom of the piston 8 lifting the conveyer a fixed amount, the initial free fall of the foot 12 compensating for any unevenness in the ground, Fig. 5 (not shown). The jack is completely retracted for transport by venting connection 18 and supplying pressure fluid to connections 24 and 17 to release the lock and lift the piston 8, the piston 10 being returned to the top of the piston 8 by the spring 13. The connections 17 and 24 are then vented, the spring 22 locking the piston 8 in position at the top of the housing 6.
